By utilizing the generalized ray matrix for spherical mirror reflection, two new sensitivity factors are introduced considering the perturbation of the optical-axis caused by the radial and axial displacements of a spherical mirror in a nonplanar ring resonator. Based on this, a novel way for finding the location of the singular points of the sensitivity factors is presented. It is found that some nonplanar ring resonators with the effective modes may have the singular points of the sensitivity factors. The unsuitable regions for nonplanar ring resonators are also obtained from the perspective of the sensitivity factors.
通过利用球面镜反射的广义光线矩阵，考虑了非平面环形谐振器中球面镜的径向和轴向位移引起的光轴扰动，引入了两个新的灵敏度因子。基于此，提出了一种寻找灵敏度因子奇异点位置的新方法。发现一些具有有效模式的非平面环形谐振器可能具有灵敏度因子的奇异点。还从灵敏度因子的角度获得了非平面环形谐振器的不合适区域。
